Why Don't You Have To Declare Variables In Javascript?
Jul 20, 2005can anybody put forward a sensible argument javascript's behaviour of
creating a new global variable whenever I assign to a previously undeclared
variable. I can't beleive this is just for the sake of convenience (surely
we learned this much from basic).
here's my proposal: all "global" (document scope) variables must be declared
by 'var' outside a function block.
failing that, does anyone know any patterns or tricks I can use to make sure
I don't create a new global variable when I accidentally misspell a variable
name?

View 4 Replies View RelatedPossible To Declare A Default Value In A Function?
Jan 28, 2009How do i declare a default value in a function? I have a simple function
function color_input(id,token){
if (!empty(token)){
document.getElementById(id).style.backgroundColor = '#2A2A2A';
document.getElementById(id).style.color = '#DDC58C';
[Code]....
You will notice that the #2 parameter is missing in the html call. Sometimes i don't have it to send. in PHP i would just set the functions second param like token=''
function color_input(id,token=''){}
How do i set a default param in a JS function?

JQuery :: Ajax - Don't Declare XMLHttpRequest Object
Mar 16, 2011I find ajax with jquery more confusing than with regular JS, b/c in jQuery you don't declare XMLHttpRequest object.. so how do you do something like:
In example I mention here,[url] namely [url] I don't understand where var 'msg' is declared, I know it comes from the back-end, but HOW is it passed to the front-end? (how do you do this w/o responseText or something similar?)
I'm trying to connect to a send-mail jsp with ajax.. the email is not getting sent.. I want to test if the ajax connection is being made at all.. don't know how do it w/o something like xmlHttp.responseText
This is my jQuery ajax code for connecting to send-email jsp:
var dataToSend = "name=sName&email=sEmail&msg=sMsg;

Declare Variables Once And Use Them In Multiple HTML Files?
Jan 7, 2011I have been working on a few budget scripts that I can access from the web in using HTML. My problem is that when variable values change I need to change these values in all of the HTML files on the server. I know that there is a way to declare global variables in a single file and use those values in another file but I have not been able to find any information that tells me exactly how to do this. I have tried to put it together on my own using what little informaiton I have been able to find but have not been able to get this to work. Is there a more detailed referance that I can find somewhere or does anyone know what steps I need to take to make this happen?
